The Link Between HVAC Systems and Sleep Quality

Key Takeaways:

• Your body naturally cools down as it prepares for sleep, and maintaining the right indoor temperature supports this process. The optimal sleep temperature range is between 60-67°F, according to the NIH and other expert sources.
• 80% of adults prefer to sleep in rooms cooler than 70°F, based on Mint Home’s poll.
• The best AC temperature for sleeping is one that stays consistent, typically around 65°F for most people.
• In addition to temperature, proper humidity levels (30–50%), clean air, and consistent airflow also contribute to sleep quality.
• Regular HVAC maintenance ensures your system runs quietly and efficiently, which can reduce nighttime disruptions.
• MintCare, Mint Home’s HVAC maintenance plan, helps homeowners avoid breakdowns and keep their systems running at peak performance.
• Using your HVAC system strategically, paired with breathable bedding and smart thermostat settings can create a healthier, more restful sleep environment.

Getting a good night’s sleep isn’t just about your mattress or bedtime routine. The air circulating in your home plays a critical role in helping your body achieve and maintain its optimal temperature for sleep.

Research from the National Institutes of Health (NIH) shows that your body naturally cools down as you prepare to sleep. This drop in temperature signals to your brain that it is time to sleep. Maintaining a consistent air temperature in your bedroom helps to support this innate process. If the air in your home has poor circulation or is too warm or cool, it can disrupt your body’s thermoregulation, making it harder to fall and stay asleep.

What’s the Optimal Air Temperature for Sleep?

Research from the NIH suggests that a cool bedroom is ideal for quality sleep. The recommended range of temperature for most people is 60-67°F, as this temperature range has been shown to help the body maintain its natural nighttime cooling process. Temperatures outside of this range can possibly disrupt sleep stages, such as REM and slow-wave sleep (SWS), both of which are crucial for your body’s recovery.

To better understand how real-world preferences align with these recommendations, we conducted a poll asking 75 adults about their ideal sleeping temperature. Here’s what they said:

• 20% prefer temperatures below 60°F
• 24% of respondents chase the range of 60-65°F
• 36% favored 65-70°F
• 19% enjoy 70-75°F
• 0.01% of respondents preferred temperatures above 75°F

These results show that the majority of people (80%) favor cooler temperatures under 70 degrees fahrenheit when sleeping, which aligns with expert research. This highlights the importance of using HVAC systems to maintain a cool and stable environment for optimal rest.

What’s the Best AC Temperature for Sleeping?

Experts agree that the best AC temperature for sleeping falls between 60 and 67°F. This range supports your body’s natural ability to cool down, which is critical for entering deep, restorative sleep.

A lot of people don’t realize how HVAC settings play a central role in quality sleep. If your bedroom tends to fluctuate or feel stuffy overnight, even a well-timed smart thermostat setting may not be enough. Fine-tuning airflow, humidity, and ventilation all play important roles.

When selecting the best air conditioner temperature for sleeping, consistency is more important than choosing the absolute lowest number. A nighttime setting around 65°F for most strikes the right balance between comfort and efficiency.

How HVAC Systems Support the Ideal Sleep Environment

Your heating and cooling system is a powerful tool for creating the perfect sleep environment. Here’s how your system works to support your body’s natural thermoregulation and overall comfort:

1. Temperature Control: You can set your smart thermostat to automatically adjust the temperature at night to match your body’s needs for sleep. Keeping your thermostat between 60-67°F can aid you in a restful night's sleep.

2. Humidity Regulation: Controlling humidity is equally as important as temperature. High humidity can make the air feel warm and sticky while low humidity can dry out your skin and respiratory system. For the ideal climate it is best to maintain humidity levels between 30-50%.

3. Consistent Airflow: Ensuring your vents are unobstructed and using fans to evenly distribute air can help maintain your ideal bedroom temperature. Proper air circulation prevents temperature fluctuations and enables your bedroom to stay cool and comfortable throughout the night.

4. Air Quality: Replacing your heating and cooling systems air filters regularly helps reduce odors, allergens, dust, and pollutants circulating in your home. Clean air promotes better respiratory health and aids in your sleep.

If you’re unsure where to start, a good rule of thumb is to program your system around the best air conditioning temperature for sleeping, then adjust for comfort as needed. Even a few degrees can make a difference in how refreshed you feel in the morning.

Regular HVAC maintenance can also ensure your system runs efficiently, quietly, and reliably, three things that directly impact sleep. A unit that cycles frequently or makes disruptive noises may need a professional tune-up. At Mint Home we offer MintCare our maintenance plan to ensure your system is always running at peak efficiency and to catch minor issues before they turn into system failures.

Combining precise temperature control, consistent airflow, balanced humidity, and keeping up with maintenance, your HVAC system can transform your bedroom into a sleep sanctuary. Pair these with a breathable bedding to enhance the effects of your HVAC system and you will be well on your way to a restful night’s sleep.

Is Your HVAC System Living Up to Your Sleep Standards?

If your current heating and cooling system is not positively contributing to your ideal sleep environment, whether you’re experiencing inconsistent temperature, poor air circulation, or humidity issues, it might be time for an upgrade. Upgrading your HVAC system gives you the tools needed to create a healthier and more comfortable sleeping environment.
